ECODELTA panels, read off the datasheets

EcoDelta is a French developer of wind and solar energy projects. They offer expertise in project management and financing to maximize energy output. The company strives to promote, develop, and operate decentralized renewable electricity projects.

Everything below is computed from those 13 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where ECODELTA does not publish a figure, it is left out of the average rather than assumed.

The top of the range

The leaders of ECODELTA's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof.

By what the array is for

Three cuts of the same catalogue, each ordered by efficiency inside its band. An empty column means the brand does not build for that case.

For a house roof 380-460 Wp
1 ECO-450M-54LHC-DGBF Monocrystalline bifacial 450 Wp 22.5% 2 ECO-445M-54LHC-DGBF Monocrystalline bifacial 445 Wp 22.3% 3 ECO-440M-54LHC-DGBF Monocrystalline bifacial 440 Wp 22.0% 4 ECO-415M-60SB Monocrystalline 415 Wp 21.2% 5 ECO-410M-60SB Monocrystalline 410 Wp 20.9%

What the catalogue is made of

Cell technology across the market

Shares are of the 13 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.

Cell technology share of the catalogue
TOPCon 61.5% 8 PERC 38.5% 5
TOPCon accounts for 61.5% of the catalogue - 8 of 13 modules.

Strengths and gaps

Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built.

What this catalogue is good at
  • High-efficiency panels available (up to 22.5%)
  • Strong warranty coverage averaging 26 years
  • Established manufacturer with 24+ years of experience
